Celestial Objects for Star Party Sessions
Celestial Objects for Star Party Sessions
January | September | October | November | December
To see generally where constellations are in the sky, get a sky mobile app, planisphere or
make your own planisphere with interchangeable star wheels (especially the Messier star wheel).
These month-by-month lists were compiled by Alan Gould as ideal objects to find
with an eVscope, ES Astro 53 Pro, or other "smart scope".
